NITED STATES WILLIAM FRANKLIN OLINE AND PHILIP DAVID WEAVER, OF BENDERSVILLE7 PENNSYLVANIA; 'SAID WEAVER ASSIGNS HIS RIGHT TO SAID CLINE.

IMP ROV EMENT IN MACHINES-FOR BORING POSTS.

Specification forming part of Letters Patent No. 120,941, dated November 14, 1871.

To all 'whom tt may concern:

Be it known that we, WILLIAM FRANKLIN OLINE and PHILIP DAVID WEAVER, of Benders- Ville, in the county of Adams and State of Pennsylvania, have invented an Improvement in Machines for Boring` Posts; and we hereby declare the following to be a full and eXact description th ereof, reference bein g had to the accompanying drawving forming part of this specification.

The nature or essence of our invention consists in a peculiar novel construction and arrangement of borin g-machine for boring holes in fence-posts.

Upon a suitable frame, A, is a slide, B, upon which the fence-post is vclamped by means of the clamping-lever O. This slide is moved to and fro by means of two straps, D, which wind upon and nnwind from the pulley-,shaft E, which is operated by means of a crank, F. By this arrangement the postis moved endwise when desired to set the anger for` anew hole. The slide B is provided with notches b, into which the spring-catch S looks, and thus holds the post from slipping while the auger is at work. These slides B work so as to move the post in either direction. A carriage, G, is arranged to travel upon the frame A toward and away from the auger H, which has no longitudinal motion,bnt may be raised and lowered by means of lever I, which acts upon the auger-holder K. The carriage Gr is moved back and forth'by means of two treadles, L, acting` in opposite directions, in connection with cord M passing around a common pu-lley, N, and then over the two already-mentioned pnlleys O and i'. We do not confine ourselves to the precise constr-nction above described, as cog-gear may be used, (thoug'h this is more extensive,) and other slight changes may be made without departing from our invention.

Having described our invention, we clai1n The slide B, with its clamping-lever O movcd lengthwise by the shaft E, cords D, and crank F, and moved laterally by the pulley-cords and treadles, in combination with the auger H, substantially as set forth.

PHILIP DAVID WEAVER. WILLIAM FRANKLIN OLINE.
